I installed IBM WebSphere Registry and Repository this evening. The installation took a little longer than I had anticipated. Mostly due to my rushing through the WAS 7 setup and not having the ND node configured properly. I also had an issue with a 32-bit JVM in my path causing some issues. I installed WSRR V6.3 FixPack 1.
Operating System: AIX 6.1
Database: DB2 UDB V9.5
Application Server: IBM WebSphere Application Server Network Deploy 7.0.0.5
